GRAPPLING HOOKS

Use this Stratagem at the start of your Movement
phase. Select one of your INFANTRY units.
For the duration of your turn, models in that
unit can ascend or descend ruins or Sector
Mechanicus structures when they move, even
without a ladder, wall or girder.
Furthermore, for the duration of your turn, do
not count any vertical distance that unit moves
against the total they can move that turn
(i.e. moving vertically is free for those models).
